This 1.73ct lab-grown cushion sits in the one-and-a-half to two carat band, graded H colour (near-colourless) and SI1 clarity (slightly-included), with a standard cut grade and certified by IGI LG538290301 or 538290301. Listed at 9 retailers as of October 30, 2026, with prices from $444 to $1,968, a $1,524 spread on the same certified stone. MOH London lists it at $1,968. Cut grade matters more than carat or clarity for visible brilliance. If you can shift budget toward an Excellent or Ideal cut, do it before chasing higher colour or clarity.
